When a movie theater in Austin, Texas hosts a special screening of Wonder Woman in a few weeks, there will only be one rule — no boys allowed.

This afternoon, the Alamo Drafthouse theater announced a women-only screening of the upcoming film, saying it was “embracing its girl power.” And when they mean women-only, they’re serious. “Everyone working at this screening — venue staff, projectionist, and culinary team — will be female,” the theater announced on its website.

It’s a fitting concept since the movie is based around an Amazonian princess who lives on an island without men. But apparently, not everyone feels that way. As reported by BuzzFeed, the idea of a screening just for women had some dudes pretty heated.

“Apparently ‘equality’ is only selective nowadays,” one commenter on Facebook said. “How about a "men's only" showing of a movie or is that not how equality works?” But the theater isn’t fazed by the haters. “This has zip to do with equality,” it responded. “This is a celebration of a character that's meant a great deal to many women since 1940.” When another user asked “Will there be a male only viewing?” the theater clapped back, providing a link on renting a room out for a private event.

But the thing is, men’s-only clubs are still a thing and have been for centuries. But things are changing and, in addition to some “gentlemen’s clubs” beginning to admit women as members, women-only workspaces are popping up around the country, the New York Times reported.

The Wing, a workspace and social club exclusively for women, opened last year in New York City and has been thriving since. “There is a culture in these co-working spaces that is sort of bro-centric, male-dominated,” the club’s co-founder, Audrey Gelman told The Cut about the space. “There was this blind eye to amenities that were essential for women.”

It should be noted that this isn’t the first time men have expressed anger about the new Wonder Woman film. After the internet took a good minute to talk about actress Gal Gadot’s underarms, it was pretty hard to ignore the fact that some of the loudest critiques were mostly from men.

It doesn’t look like the hate will affect the movie’s numbers, though. The Alamo’s women-only screening sold out so fast, they added a second women-exclusive one — which also sold out. And according to its Facebook page, the theater is working on adding more. An Alamo Theater in New York City also followed suit, announcing a women-only screening with proceeds benefiting Planned Parenthood. It also sold out almost instantly.
